ここテスト出るよって英語でなんて言うの？

「この内容はテストに出ますよ」という意味の表現です。「be on the test」が「テストに出る」という意味になります。また、文法的に「going to」が未来の予定や確定的な計画を表すときに使いますが、これを「will」に変えても同じ意味になります。また、「might be」を使うと「テストに出る可能性がある」という、未定な状態を表せますね。

例えば、
"This might be on the test."
「これはテストに出るかもしれません」

という表現が可能です。

さらに異なる表現としては、
"This will probably come up in the test."
「これはおそらくテストに出ます。」

このような風にも言い換えることができます。

また、テストについて尋ねるときは、
"Will this be on the test?!"
「これってテストに出ますか？」

私が学生の頃はよく先生に、

"Will this be on the test?!!"
「ここテストに出ますか？！」

と聞いたものです。。

「これはテストに出るよ！」は"This will be on your test"と表現できます。

さらに、
"Make sure you review this part!"「ここはちゃんと復習するんだよ」
と付け足せば生徒の準備もバッチリですね。

【テストされる】と考えるとこの文は理解しやすいですね。
【on this】の【on】は【関して】の意味ですね。
➡【ここに関してテストされちゃうよ】って感じですね。

This part will be on the test =ここテストに出るよ

The teacher will definitely put this on the test =これ絶対先生テストに載せるよ

確かではないけど「きっとこれ出るだろう」と確信している時にはこう言う表現も出来ます。

If you would like to explain to someone that a certain part will be tested, you can say "This particular chapter/part will be on the upcoming test." or "This part of the subject will be tested on your next examination." These are some good ways to easily explain this to someone.
